On 10 November 2022, a De Havilland Canada DHC8-200 started engines with the left engine propeller restraint strap attached and as it became airborne from Sydney, the strap was thrown free from the propeller, impacted the fuselage and the associated securing pins penetrated the fuselage, one injuring a passenger. The aircraft returned. The Investigation attributed the occurrence to a comprehensive failure of both pilots to follow relevant standard operating procedures within a context of regular related procedural non-compliance. The operator’s failure to properly involve their contracted airport handling agent in effective management of operational safety matters was also noted.
